When you realise the French have had the better of the action AGAIN.

 

That'll be the reaction of those who get wet mess and one weak cloud fart.

Storm & Convective Forecast

Issued 2017-05-28 22:08:52

Valid: 28/05/2017 18Z to 30/05/2017 06Z

CONVECTIVE/ STORM 2 DAY OUTLOOK- 28TH / 29TH

Synopsis

Upper trough axis approaches EIRE, Bay of Biscay and Iberia from the west Sunday night into Monday morning, as upper ridge extending north from the Mediterranean across Central Europe begins to relax. A plume of warm, moist and unstable air will spread north from France during Sunday evening/night across southern U.K., with thunderstorms likely on the leading edge of the plume as is to arrives overnight. Storms will clear away NE and weaken Monday morning, though diurnal heating of warm humid air across SE UK on Monday could trigger some isolated thunderstorms.

DAY 1 OUTLOOK - UNTIL 06Z MONDAY 29TH MAY

... S ENGLAND SUNDAY NIGHT ...

As upper trough approaches from the west, colder air aloft from the west overrunning warm moist conveyor ahead of surface cold front to west of France combined with large scale ascent is triggering a cluster of thunderstorms across NW France and into western English Channel this evening. These elevated storms are quite electrically active and are modelled to grow upscale into a MCS, given increase in southerly low-level jet and around 40-50 knots of deep layer shear. This MCSs will likely track into southern England tonight, bringing locally torrential,rain leading to flash flooding, frequent cloud-to-ground lightning, strong and isolated damaging wind gusts and also isolated large hail. Storms should weaken later in the night as they move away NE from southern England into more stable environment.

DAY 2 OUTLOOK - 06Z MONDAY 29TH MAY - 06Z TUESDAY 30TH MAY 

... S ENGLAND, MIDLANDS, LINCS AND E ANGLIA ...

Atmosphere will likely be largely turned over by overnight storms, however, residual mositure and surface heating combined with breeze convergence along a diffuse cold front may trigger isolated thunderstorms during the afternoon across the above areas. Localised torrential rainfall leading to flash-flooding, isolated large hail and gusty winds are possible from any storms.

You means MCS? I've seen an MCC in Nigeria and they are bonkers. Our hotel pool was levelled by the rainfall.

 

The satellite image looked like MCC but it was not, sorry. 

[chionomaniac]

It's getting closer.... I have seen numerous flashes to my south and lightning now less than 20km away from south coast

[Thunderstruck]

Is it me or does it seem to be heading almost due East now?

 

Edit: Maybe not...

Go just past Beachy Head Pub several car parks facing Seaford, execellent location!

Thanks for that Callie, I am *seriously* considering it now! Getting things together, camera etc and getting postcodes at the ready for the satnav. If this doesn't look like dying down and it continues the marsh towards Brighton way, I'll hit the road.

Hold fire. It's tracking 020-030° if I'm getting very good visuals of lightning. You'll be in line.
